Garmin EchoMAP Ultra 125sv with GT54UHD-TM Transducer


The ECHOMAP Ultra 125sv combo, with its bright, sunlight-readable 12” keyed-assist touchscreen display, has all the tools you need for successful fishing.

It includes an all-in-one transducer for CHIRP traditional and Ultra High-Definition ClearVü and SideVü scanning sonars.

It also includes preloaded BlueChart coastal charts with Auto Guidance¹ technology.

1Auto Guidance is for planning purposes only and does not replace safe navigation operations.

The ECHOMAP Ultra 125sv combo also supports optional Panoptix LiveScope LVS12 sonar (no black boxes required) plus the full line of Panoptix all-seeing sonar transducers.

It also supports the Panoptix LiveScope system.

When you’re off the water, it’s easy to keep your ECHOMAP Ultra combo safe and secure.

You don’t have to mess with plugging and unplugging wires from the unit, because the cords plug directly into the quick-disconnect bail mount.

This allows you to quickly install and remove your ECHOMAP Ultra from power and the mount.
